Areas of Application

This additive is suitable for all gasoline engines equipped with a catalytic converter. It is important to note that deposits in the catalytic converter based on manganese oxide cannot be removed.

Application Instructions

For optimal results, follow these steps:

Pour the additive into the LIQUI MOLY Pump-Spray Bottle (part no. 3316).
Pump the spray bottle to establish pressure.
Access the intake tract, ideally just behind the turbocharger and immediately after the air-flow sensor.
Start the engine and spray the additive into the intake tract at short intervals while maintaining a moderate engine speed of 2,000-3,000 rpm.
If the engine speed does not fluctuate, you can extend the intervals between sprays. If it fluctuates significantly (>700 rpm), shorten the spraying duration.
For best atomization, regularly check that the pump-spray bottle maintains adequate pressure.

For enhanced cleaning of the fuel system, we recommend adding Catalytic-System Clean (part no. 7110) to the fuel right after applying this additive to ensure a comprehensive clean.

This product is available in a 300 ml can (SKU: 8931).
